The present invention relates to a method for forming a capacitor having carbon or metal electrodes and an electrolyte which is also a source of electropolymerisable anions. Applying a sufficiently positive voltage, a thin dielectric layer forms at the positive electrode, enabling the use of cell voltages higher than 3.5 V. The construction and characteristics of capacitors with 5, 6.3, and 10 V of cell voltages, having reduced graphene oxide electrodes and an ionic liquid electrolyte, are shown. Further, a method of forming a capacitor, including the steps of: (a) providing a first electrode; (b) providing a first electrolyte including an anionic compound, wherein said compound includes at least one cyano group or at least one nitrile group; (c) electropolymerising said anionic compound in order to form a dielectric layer on at least part of the first electrode; (d) forming a capacitor including the electrode of step (c), a second electrode and a second electrolyte, which is the same or different to the first electrolyte, is claimed. In a further aspect of the invention, there is provided an electronic device including a capacitor, a transistor or an electrode produced by means of a method as defined above. It is believed that a number of dielectric compounds produced by the method as defined above are new compounds not previously isolated. Accordingly, polytetracyanoborate, polycyani, or polytricyanomethanide.

A carbon paste including a carbon powder, a resin, and an oxygen releasing oxidizer. The amount of the oxidizer is 3 to 30 parts by mass based on 100 parts by mass of the total amount of the carbon powder and the resin. A solid electrolytic capacitor element is prepared by a method which includes making a valve-action metal powder sintered to obtain an anode body, electrolytically oxidizing a surface of the anode body to chemically convert the surface into a dielectric layer, electrolytic polymerization to form a semiconductor layer of an electro conductive polymer on the dielectric layer, applying the carbon paste onto the semiconductor layer, and drying and hardening the carbon paste to form a carbon layer.

A thermally stable component formed of a tempered aluminum alloy casting which reduced costs is provided. The aluminum alloy typically has an elongation of at least 8% after casting, which is preferred for self-piercing rivet processes. The aluminum alloy leaves a casting facility in the as-cast (F temper) condition. The cast aluminum alloy is then shipped to another entity, such as an OEM, and is subjected to an artificial aging process, such as on the OEM's existing paint line, rather than at the casting facility. The artificial aging process typically includes electrodeposition coating and curing. The components that can be formed by the reduced cost method include lightweight automotive vehicle components, including structural, body-in-white, suspension, or chassis components, such as front shock towers, front body hinge pillars, tunnels, and rear rails.

A switchable hydrophilic surface is created by attaching electrochemically switchable hydrophilicity polymers to the surface of a microelectrode array. Ferrocene polymers are one example of electrochemically switchable hydrophilicity polymers. Activation of electrodes in the microelectrode array changes the oxidation state of metal ions which switches the polymers between hydrophobic and hydrophilic conformations. Selective activation of electrodes can create patterns of wettability on the microelectrode array that may be varied in real time. The switchable hydrophilic surface may be used to control solid-phase synthesis of polymers. Growing polymers may be selectively extended at locations on the microelectrode array that are hydrophilic. The pattern of hydrophobic and hydrophilic regions can be changed during sequential rounds of synthesis to create a variety of different polymers at different locations on the surface of the microelectrode array.
